130°C Heat Sealable Polypropylene Disk

130°C Heat Sealable Polypropylene Disk offers a controlled seal initiation temperature, enabling reliable thermal bonding in packaging, sealing, and lamination processes. Produced from polypropylene copolymers or multilayer structures, it provides a combination of excellent water vapor barrier properties, good mechanical strength, and chemical resistance. These disks are widely used in food packaging, medical device sealing, and laboratory sample containment, where consistent and secure closure integrity is critical. Specific applications include heat-sealed container lids in sterile packaging, tamper-evident seals for pharmaceuticals, and protective closures in chemical reagent storage. In research and manufacturing, they facilitate advancements in controlled atmosphere packaging and micro-environment sealing, enhancing both product safety and shelf life. Their ability to deliver consistent sealing performance at moderate temperatures while retaining durability positions them as an essential material in both scientific development and industrial-scale production.
